Piston servomotor dismouting device

The utility model relates to a piston servomotor dismouting device, it includes: the spanner is strikeed to the combination formula, has the bar body, the through -hole is established to the tip of body, and the middle part is established and can be overlapped in order to drive piston rod pivoted mesopore on the piston rod, chain block, the rotation of strikeing the spanner for the combination formula provides traction force, and wire rope, one end can be fixed in the through -hole of this end of body, the other end by chain block pulls. Through above -mentioned technical scheme, only need tostrike the spanner cover with the combination formula and on the piston rod, connect gradually chain block, wire rope and spanner through -hole department, pull the spanner through chain block and candrive the piston rod and rotate, save time, laborsaving, overall structure is simple, light in weight, the safe and reliable during use to repeatedly usable. 本实用新型涉及种活塞式接力器拆装装置，其包括：组合式敲击扳手，具有条形本体；本体的端部设通孔，中部设可套在活塞杆上以带动活塞杆转动的中
